The Theoretical foundation of stars

Twinkle twinkle little star

There aren't many kindergarten rhymes concerning astronomy. Although 'twinkle twinkle little star' builds constructive point. We are able to tell which lights in the night sky are stars since they emerge to twinkle. Planets, on the other side, don't, they stand out progressively in the sky.

Stars twinkle since they are very distant away, and so come into sight as minute points of light in our night sky. Some of this light is engrossed by moving air in the Earth's atmosphere, making the star appear to sparkle.

Planets, like Saturn or Jupiter, don't glitter. This is because they are a much closer to the Earth and so they seem to be bigger in our sky than stars.
